With the continuous growth of oxygen demand in the global medical health and industrial fields, pressure swing adsorption (PSA) oxygen generator has become the mainstream choice in the market with its high efficiency and energy saving. This article will introduce the basic configuration, working principle and core application scenarios of PSA oxygen generator in detail.
Working principle of PSA oxygen generator
According to the principle of pressure swing adsorption, zeolite molecular sieve is used as adsorbent. Due to the selective adsorption characteristics of zeolite molecular sieve, nitrogen is adsorbed by the molecular sieve in large quantities, and oxygen is enriched in the gas phase. Nitrogen and oxygen are separated under the action of pressure swing adsorption. A double-tower or multi-tower structure is adopted, while oxygen is adsorbed and regenerated. The opening and closing of pneumatic valves are controlled by intelligent programs such as PLC, so that two or more towers are cycled alternately to continuously produce high-quality oxygen.
Basic configuration of PSA oxygen generator
Core components
- Air compressor: Provides raw air, which must meet the requirements of oil-free and clean to avoid contaminating the molecular sieve.
- Air storage tank: stabilizes air flow pressure and reduces compressor load fluctuations.
- Filtration system: includes primary and high efficiency filters to remove dust, moisture and oil from the air.
- Adsorption tower: built-in zeolite molecular sieve (such as 13X type) to separate nitrogen and oxygen through pressure swing adsorption.
- Control system: PLC or microcomputer automatically adjusts pressure, flow and purity, and supports real-time monitoring.
- Oxygen buffer tank: stores finished oxygen to ensure stable output. 2. Optional additional modules
- Oxygen flowmeter: accurately adjusts output (usually 1-100Nm³/h).
- Purity monitor: ensures oxygen purity of 90%-95% (medical grade requires ≥93%).
- Silencer: reduces operating noise to below 60 decibels.
